Formal charges were filed this week against Montgomery County Republican Committee's ex-chairman Robert J. Kerns, alleging that he served Ambien-laced wine to a woman who worked as a paralegal at his law firm and then raped her unconscious body.

Kerns then allegedly drove the drunk woman home, handing her a tainted, $68 bottle of Chardonnay on the way and waiting her to pass out.

"At some point between the time she drank the wine provided by Kerns and lost consciousness and the time she regained her memory as they entered her neighborhood, the victim has a vague memory of her head up against the car window and pushing Kerns away," said the report.

After "forcibly and violently violat[ing] her body" in the car, Kerns then reportedly took the woman inside the house, where he proceeded to rape her multiple times.

Montco District Attorney Risa Vetri Ferman noted that "critical forensic evidence" was collected when the victim visited the hospital the following day.
